海绵城市建设——低影响开发绿色雨水设施的植物运用

Sponge City Construction——Plant Application of Low Impact Development of Green Rainwater Facilities

当前,我国海绵城市建设正在如火如荼地开展,许多城市均对低影响开发绿色雨水设施的建设进行了大量的研究与实践。海绵城市建设中绿色雨水设施的运用应因地制宜,结合具体城市的气象、水文、土壤及植被情况,有针对性的建设实施,实现对径流和水质的控制,达到海绵城市建设的任务要求。植物作为绿色雨水基础设施的重要因素之一,其合理的选择与配置更是维持雨水设施性能长期有效的关键。雨水设施中植物的选择,要根据其结构和功能的要求,充分考虑水分、淹没时间、场地尺寸等特殊条件,选择适合其生长环境的植物种类。此外,根据场地设计的目标与要求,还应从植物的平面布局、色彩、形态等方面进行配植设计,达到美化环境的景观要求。

It has been a trend to build an increasingly number of sponge city in China recently, and a lot of research and practice have been undertaken to explore the ideas of utilizing green infrastructure to better stormwater management. The green stormwater infrastructure in sponge city should be designed with the considerations of local urban conditions, including climate, rainwater, soil and vegetation, and its specific strategies should aim at having a more efficient management of running water and water quality, which will meet the requirements of sponge city. As an essential component of green stormwater infrastructure, plants must be selected and planted in a proper way, which will be a key to improve the efficiency and duration of stormwater infrastructure. The planting layout and plant species should consider a range of factors, from the overall layout and function of stormwater infrastructure to some unique details including moisture, flooding time and site scales. Besides, according to the goals and requirements of design, the planting plan, plants color and shapes are also important aspects to consider in design, which will result in an attractive environment.
